how do you change the distance on a baseball that tells the speed made by velocity?

Question

I need help

Answer 1

buy a new one, these measure based on time from throw to the impact of the ball in the glove, so they are really not measuring speed at all, only giving an estimate based on how long the ball as moving, which is based on a set distance. To go from a 90ft diamond to a little league or vice versa you would need a different ball.
As for that other guy's "education", speed and velocity are not the same thing. One is a scalar quantity and the other is a vector.

Answer 2

You can't. There are no baseballs made that tell the speed made by velocity. And since velocity and speed are the same thing, you're illiterate question is also redundant. (Sorry for using big words, but then, that's what happens when you get an education.) Go see an English teacher and ask for help rephrasing your sentence into comprehensible language.

Answer 3

Your question is unclear. If you want to change the speed you throw a baseball..other than more strength; increase or decrease how tightly and how many fingers you place on it. The more friction, the slower the ball will go. If you want to increase speed..hold it as gently as an egg, yet enough to hold on to it.
